wbemdisp: Remove unused IUnknown *outer parameter from object constructor.

[Dmitry Timoshkov]

The patch also fixes a memory leak in the object creation failure case.

Class factory explicitly checks for it:

if (outer) return CLASS_E_NOAGGREGATION;
obj_constructor(outer, &obj);

i.e. outer is always NULL in the object constructor.
